My parents divorced quite recently, just few years ago after being rather unhappily married for 26 years. My mom caught him cheating. I got engaged a few months ago and a month later with little notice my father married the woman who he was with when my mom caught him. I live in a different country so only met her and her family a few times, they were very nice to me, my father is very happy. I am polite / neutral with her. On the contrary my mom is not doing great at all, she is still in a complete breakdown and a month after engagement she made a scene that she does not want my father at my wedding and hang up on me. When she found out i speak to his new partner she refused to talk to me ever again. It’s been a couple of month now, i tried to reach out but she blocked me. My mom is not really a very reasonable type, i try to take care of her and cheer her up but I cant just sit and talk to her peacefully, it is always a drama when it comes to my father. My grandparents are on her side. I mentioned to my father that i will not be inviting his wife as i don’t feel comfortable making the whole situation much worse and also because i really dont know her well to which he said that he may not be coming then.
What do I do about it? It looks like it maybe the case that neither of my parents will come or if my father comes with his wife i may never be able to fix the relationship with my mother....

I'm so excited to finally, after 9 years, getting married again! He's so amazing and we want to have an amazing wedding in Jamaica next year. Allow me to introduce myself: I am Katherine, his grandchildren will call me KitKat! who is marrying a minister that truly leaves me speechless at times the way he loves and cares for me. Professionally, I am a destination wedding planner/travel agent/award-winning floral designer, so this wedding will be my ENCORE. Last night, we started out with 50 guests, relatively the larger size of most destination weddings. Then our guest list grew to 100. Right! My team right now, does have a contact in Jamaica, that I'm already working with. We are working on the budget, constantly. The plan is to have all of the details together before Thanksgiving holiday, so that family and friends can prepare to start booking.
